With the onset of lactation, dairy cows have to mobilize body reserves, mainly body fat, to cover the output of energy via milk. The homeorhetic metabolic adaptation to the needs of milk production is accomplished through ...

Poor oocyte developmental potential contributes to reduced fertility in livestock species and hampers the application of biotechnology techniques in cattle industry that could be used for spreading certain genotypes with ...

Fertility is one of the most important economical traits in swine production. Implementation of artificial insemination (AI) in swine production allowed improving selection on the boars for production traits, but at the ...

Inverted teat reduce the number of functional mammary complexes in affected sows leading for reduction of piglet productivity and litter growth during the lactation period. This detect occures in commercial pig breeds with ...

Background: The effect of space flight conditions on the immune system of humans and rodents was investigated since the beginning of space flight. Until now there were no investigations of the influence of microgravity ...

Homeobox (hox) genes encode transcription factors which regulate the expression of several target genes encoding essential proteins for cell differentiation and proliferation. Thus, hox-genes have long been recognized as ...

In the present thesis, genome scans were performed for QTL detection in a F2 resource population which was reciprocally crossed between Duroc and Pietrain. 1085 F2 progeny within 38 full-sib families were produced from ...

MicroRNAs are the major class of gene regulating molecules playing pivotal roles at post-transcriptional level. Identification and expression profiling are the initial steps to understand their regulation of biological ...

Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ...

Mit der vorliegenden Dissertation soll das ökologische Beziehungsgeflecht der Elsbeere (Sorbus torminalis) erfasst werden, einer in Deutschland seltenen, in zerstreuten, kleinen Populationen vorkommenden Baumart (Fam. ......
